iphone - How to apply black and white effect to a color video in iOS

In my application I have a color video which I want to make as black and white video. Is there any framework that supports this in iOS? If so, how to implement that effect on color video?

Can anyone help in this regard?

A bit late here, but you should check out OpenCV.

It can be compiled as a static lib for the iPhone and can convert video (frame by frame) to grayscale or two color.

You can start here. There are other resources for doing this floating around.
